I tried to flash a wrong image and now the FireFly RK3288 doesn’t start anymore.
The only way to have it running is using MaskRom.
Problem is: after I get MaskRom, what am I supposed to go ahead? Should I add a new bootloader? Can I flash an image from scratch without doing something else?
Just flash the firmware (update.img) file. The upgrade tool will take care of everything, including flashing the new loader, booting from new loader and flashing partition images.
